In the Database On Table Row operation, what does the Watermark column enable the On Table Row operation to do?

Suggested Answer: A Vote an answer

The correct answer is To avoid duplicate processing of records in a database.
If a watermark column is provided, the values taken from that column are used to filter the contents of the next poll, so that only rows with a greater watermark value are returned. If an ID column is provided, this component automatically verifies that the same row is not picked twice by concurrent polls.
